When is was a kid, my mom took me to Nordstrom and the ladies at the makeup counter told me what to buy and showed me how to apply it. I’ve done it a couple of times as an adult with success. I think other places, like Ulta, might do it too (but I’m a creature of habit).

As for the blush - I find a color that mimics what I look like after exercising. Then apply the blush to those areas - but in smaller quantities. I feel like it looks better on me than the whole contouring thing. Also, I test anything before I wear it out (like play around before I wash my face at bedtime).
